Ugh. I'd only be sentient during winter. No thanks.

You're sentient as a tree too, though in a sufficiently tree-like way that you don't go nuts from not being able to move. It's maaagic.

I would love this... I am mainly nocturnal anyway and I would get to live twice as long!

you extend your life significantly by migrating to one of the polar circles and being exposed to sunlight for days/months at a time

If you're wanting to remain a tree deliberately I'm sure it would be possible to rig up suitably sun-like artificial lighting to do it for as long as desired.
